针对筒基平台在中舱破舱情况下的静水拖航过程进行试验研究,分析破舱下沉及打气上浮过程中结构的运动性态,并对比不同航速条件下结构的拖航稳性,得到了中舱破舱情况及不同航速对结构拖航过程的影响。试验结果表明,中舱破舱对筒基平台的拖航稳性影响较小,因此可对结构进行优化,即将基础中舱与大气连通,以获得更好的下沉效果。
Abstract
The towing process of bucket foundation platform under the condition of damaged middle compartment is experimentally studied. The motion behavior of the structure during the damaged sinking process and the inflated raising process is analyzed. The towing stability of the structure under different speed conditions is compared. The effects of the damage of the middle compartment and different speeds on the towing process of the structure are obtained. The test results show that the damage of the middle compartment has little impact on the towing stability of the bucket foundation platform. Therefore, the bucket foundation platform can be optimized, that is, the middle compartment of the foundation can be connected with the atmosphere to obtain better sinking effect.
